Radiator Caps are designed to seal the top of the radiator filler neck to prevent coolant loss, pressurise the cooling system and raise the boiling point of the coolant.
Radiator Caps are manufactured using either metal or plastic design depending on the vehicle manufacturer’s specifications.
Tridon offers an extensive range of radiator caps covering both metal and plastic designs suitable for use on sealed recovery or open non recovery vehicle cooling systems.
In a sealed recovery system the cap (double seal) allows coolant to flow to and from the recovery or expansion tank, maintaining the integrity of the cooling system.
A non recovery system does not have a recovery or expansion tank; therefore a non recovery cap (single seal) only allows the release of coolant and return of air to the system.
A non recovery cap cannot be used on a recovery system.
The radiator cap must be compatible with the vehicle cooling system; the Tridon radiator cap range has been carefully researched and engineered to suit each specific application.
Please refer to the Tridon Part Finder for the correct radiator cap for your application.
